The music contains the signature bubbling sound effect associated with Phazon themes, mixed into a chaotic cacophony of percussion and electronic sounds. Most notably, the melody contains the main theme of the Metroid franchise.

The theme was remixed in Metroid Prime Pinball for the same boss. This version is shorter and uses lower quality instruments to compensate for the Nintendo DS's lower hardware. This results in a melody that is more clearly heard through the chaotic harmonies.

The theme was arranged for Gorea's second form in Metroid Prime Hunters, with bars from the theme being heard just as Gorea transforms into its ultimate form beforehand in a slightly lower pitch. This version is also used as the theme of the Oubliette stage in Multiplayer Mode. This version has a somewhat more electronic instrumentation, like the rest of Hunters's soundtrack. In the internal "BGMSELECTLIST.DAT" file, it is titled Gorea Returns.

The theme from Prime can be heard here: [1], the theme from Pinball here: [2] and the theme from Hunters here: [3].

In the original NTSC GCN release of Metroid Prime, the player has to let the cutscene where the creature's core essence emerges play in full, or else the Metroid Prime Battle theme will be muted throughout the entire second phase.
